Know Your Water Well

Found this useful? We'd love to hear from you if there's anything you'd like to see here, or if you have any other feedback.

SimpleWater is your science and health services partner for improving home drinking water. We offer the only water test with personalized health risk analysis and treatment recommendations: Tap Score.

People in low risk areas should test at least once every three years to protect against things like deteriorating pipes or new contaminant sources. People in higher risk areas are advised to test yearly.

About Public Water System Data

PUBLIC WATER SYSTEM DATA - SDWIS

SimpleWater imports data from the EPA's Safe Drinking Water Information System (SDWIS). This data is updated at least once per month from SDWIS, but since the EPA makes no guarantees about its accuracy, we cannot do so either. If you see something strange, please let us know: contact@simplewater.us. Thank you!

YOUR PUBLIC WATER SYSTEM - SERVICE AREA MATCHING

When you enter an address into the search bar, our system attempts to find public water systems that serve the county that location is in. The geographic service boundaries for many water systems are very complex and we may not always be able to match locations to water systems perfectly. If you have trouble finding your system, let us know.

YOUR PUBLIC WATER SYSTEM - RISK EVALUATION ALGORITHM

Our Risk Evaluation Algorithm is our own and is not provided by a third party. Using 7 water utility performance and safety System Risk Factors we compare your water system to all other Public Water Systems in the USA. The factors we've included in this analysis are the following:

Unresolved Operational Violations (Those flagged as "Major" by the EPA")

Operational Violations (Those flagged as "Major" by the EPA)

For every water system, this data is sourced from the regulatory enforcement portion of SDWIS. We look at the last 5 years (60 months) of data when making our calculations.

System Risk Factors showing only 0 violations get ranked as LOW (green).

System Risk Factors in the 1st to 59th percentile for violations of that type are rated as MODERATE (light orange).

System Risk Factors between 60 and 80th percentile are rated HIGH (dark orange).

System Risk Factors above the 80th percentile are rated VERY HIGH (red).

We then display the top System Risk Factor by its overall classification and in the order of priority of the list above (with acute health violations as the highest priority). Users may expand the system cards to view all system risk factors rated MODERATE or higher.

About Groundwater Data

GROUNDWATER DATA

SimpleWater groundwater data comes from USGS and STORET databases, representing more than 300MM national groundwater monitoring results. We've made every attempt to ensure that this data represents actual groundwater like what our customers pump from their wells every day. It is a scientific fact that well water quality can vary dramatically even within very short physical distances and sometimes by season. In some cases the original data may be inaccurate and unfortunately we cannot guarantee the accuracy of these results.

YOUR GROUNDWATER - MATCHING ALGORITHM

Groundwater quality results are gathered from an approximately 20 mile radius around the location you provide. We use water quality tests from the last 10 years to display positive results, and from the last 5 years to display negative results. Positive results are results for which a parameter is tested for and found. Negative results are results for which a parameter is tested for but NOT found.

YOUR GROUNDWATER - RISK EVALUATION ALGORITHM

The risk calculation for groundwater uses the same health criteria as SimpleWater's Tap Score Water Quality Report. It integrates the concentrations discovered at a site with latest toxicological and epidemiological data to present a clear risk assessment for drinking the underlying water.

SIMPLEWATER HEALTH RECOMMENDATION

Simply put, SWR is the most stringent of all Federal and State regulations and Public Health Goals set for a given contaminant. When official regulations are not available, as with new and emerging contaminants, we use our own research and other authoritative guidelines to make a safe recommendation. For more details on how we calculate health risk scores, contact us at contact@simplewater.us.

LOW: This concentration is not thought to pose a threat to human health.

ELEVATED: This concentration is above the level thought to present some human health risks from drinking this water untreated for a prolonged period of time. Its presence in your drinking water should continue to be monitored.

MODERATE: This concentration is thought to present significant health risks to individuals drinking this water untreated for a prolonged period of time. If this contaminant is present in your drinking water, it should be reduced using the appropriate treatment technologies.

HIGH: Water with any contaminant present at this level should not be consumed without treating it specifically for the underlying contaminant. Prolonged exposure to the contaminant could represent as much as a 1 in 10,000 risk of cancer or a roughly equivalent risk to the human body.

VERY HIGH: Water with any contaminant present at this level should not be consumed without treating it specifically for the underlying contaminant. Prolonged exposure to the contaminant could represent as much as a 1 in 1,000 risk of cancer or a roughly equivalent risk to the human body.

SEVERE: Water with any contaminant present at this level should not be consumed without treating it specifically for the underlying contaminant. Prolonged exposure to the contaminant could represent as much as a 1 in 100 risk of cancer or a roughly equivalent risk to the human body.

VERY SEVERE: Water with any contaminant present at this level should not be consumed without treating it specifically for the underlying contaminant. Even short term exposure to this contaminant at this concentration should be avoided.

EXTREME: Water with any contaminant present at this level should not be consumed without treating it specifically for the underlying contaminant. Even short term exposure to this contaminant at this concentration should be avoided.
